OVERVIEWModels GF-2100-A and GF-2200-A are high quality econom-ical programmable dual-output airflow/temperature meas-urement and control instruments with options for analog airflow, temperature, alarm, and corresponding PID control out-puts for control of airflow set points. They are designed forinstallation in specified critical applications that require pre-cise measurement of air flow (down to zero flow) and tem-perature, with available PID control for air flow set point. Theinstrument includes factory calibrated probes (one with GF-2100, two with GF-2200) and an advanced microprocessorcontrolled transmitter/controller with typical sensor accura-cy of 3% of reading (4% maximum)* from 0 - 2,000 FPM.

Figure 11. GGF-22100/GF-22200-AA Airflow MMeasurement SStation

* Sensor accuracy is the calibrated accuracy of the individual sensor. The installed accuracy of the overall airflow station is application-dependent on the resulting sen-sor density; typically better than 15% of reading.

Each sensor probe is equipped with a high reliability bead-in-glass heated thermistor element, factory calibrated to NISTtraceable standards from zero flow to 2,000 FPM. The transmitter is fully independent of the probe and does not requirefield matching to the probe. An advanced microprocessor processes the raw probe signals and provides versatile pro-grammable airflow measurement and alarm options with direct LED drive or N.O./N.C. relay dry contacts, and selectableanalog output signal options. A powerful variable input signal integration option can be engaged to reduce the effectsof transient input signal variations, and an innovative Field Calibration Wizard allows for simple, automated field adjust-ment of the instrument if required. A 16 character LCD display indicates airflow, temperature, system status and is alsoused for configuration and diagnostics. Field configuration is accomplished using a simple four-button user interface.Individual airflow and temperature measurements can be displayed for use in HVAC system diagnostics.

An input signal filter with variable buffer integration can be engaged for transient flows, and a process low limit can beset to force the output to zero when the airflow rate falls below a low limit. Both features are beneficial on outside airintakes affected by transient wind gusts at low airflow rates. A simple to use Field Calibration Wizard permits one or twopoint field adjustment to factory calibration for installations that require field calibration or adjustment. The transmitterprovides two independent programmable analog outputs with full scale ranges of 0-10VDC, 0-5VDC or 2-10VDC.

INSTALLATIONInstallation consists first of installing the sensor probe(s), then installing the transmitter, and last, installing the powerand analog signal wiring to the airflow station. The following paragraphs detail the individual procedures and stepsrequired for installation of the single probe GF-2100-A and dual probe GF-2200-A. Convenient check boxes are includ-ed at each step.

Preparation ffor IInstallation1. Determine the GreenTrol factory specified location for the GF-2100-A/GF-2200-A airflow measuring station trans-

mitter and probe as indicated on the engineer's plans. Ensure that the cable supplied with the probe is of sufficientlength to reach the planned transmitter installation site. It is recommended that the probe be installed first toensure that the included cable will reach the transmitter after allowance for routing and securing the cable.

2. Carefully open the GF-2100-A/GF-2200-A package and inspect the transmitter and probe(s) for damage. If dam-age is noted, immediately file a claim with carrier. Proceed to install each GF-2100-A/GF-2200-A sensor probe asfollows:

Sensor PProbe IInstallation1. Sensor probes must be installed at the factory-specified location using the integral universal bracket attached as

shown in Figure 3. The universal bracket consists of a rubber probe clamp that is attached to the bracket using theincluded hardware. Probes can be rotated within the clamp, and the clamp can be rotated and mounted at any pointalong the 4-inch slot on the mounting bracket, thus providing complete mounting flexibility and adjustment.Assemble probe to the clamp and bracket so that when mounted, air flow is through the probe sensor opening, andin the same direction printed on the probe label.

2. Using the engineer’s plans, mark the two mounting holes for each probe bracket at the GreenTrol factory-speci-fied location where the probe(s) will be installed.

3. Drill holes suitable for the hardware that will be used to secure the bracket at two locations.4. Carefully align the bracket mounting holes with the holes prepared in the previous step.5. Secure each probe bracket and probe in two places through each bracket using suitable hardware. Adjust each

bracket mount and/or probe clamp so that the airflow arrow printed on the probe is oriented in the direction of actu-al airflow.

6. Route each sensor probe cable to the planned transmitter site and install transmitter as outlined in the TRANS-MITTER INSTALLATION procedure that follows.

Transmitter IInstallationThe transmitter is designed for use in an environment between -20° F to 120° F (-28.8° C to 48.8° C) where it will notbe exposed to rain or snow. In locations where precipitation may be encountered, a NEMA-4 enclosure must be provid-ed to enclose the GF-2100-A/GF-2200-A transmitter. Mount the transmitter upright in a field accessible location with sufficient service clearance to permit cover removal. Theenclosure (Figure 4) is designed to accept signal and power wiring at the bottom-right of the enclosure. Ensure that theplanned location of the transmitter will allow each sensor probe cable to reach the receptacle at the bottom-left of thetransmitter enclosure.1. Using the engineer’s plans, locate where the transmitter will be installed.2. Refer to Figure 4 and mark the two mounting holes located on each of the side flanges of the transmitter. 3. Drill two holes suitable for the hardware that will be used to secure the transmitter.4. Secure the transmitter in two places using suitable hardware.5. Connect wiring to transmitter as outlined in the following procedure.

Transmitter WWiringTransmitter wiring consists of connecting the 24VAC input power, the analog output signal wires and optional alarm out-put wires at the GF-2100-A/GF-2200-A. Refer to Figures 5 and 6 for additional detail. Following installation, the airflowmeasurement station is ready for operation. Custom setup options (other than the default values) can be entered in theGF-2100-A/GF-2200-A Transmitter Setup procedure detailed later in this document.

Power TTransformer CConsiderationsSelect a 24 VAC transformer based on the maximum power requirements of the transmitter (8VA) to ensure that the oper-ating supply voltage to the transmitter (when powered “ON” with probe connected) is not less than 22.8 VAC or greaterthan 26.4 VAC.

Power CConnections1. Remove the four cover retaining screws at each corner of the transmitter cover in order to gain access to the trans-

mitter Wiring Terminal Block on the main circuit board shown in Figure 5.

2. Remove cover from the transmitter enclosure. Observe the following precautions when wiring the transmitter:

CAUTION

To pprevent ddamage tto tthe GGF-22100-AA/GF-22200-AA, ddeactivate 224 VVAC ppower ssource uuntil aallconnections tto tthe iinstrument aare ccomplete.The 224 VVAC iinput gground ((GND) cconnection aat tterminal 66 iis sshared wwith tthe AAnalog/PID OOutputsignal ggrounds aat tterminal 22. IIf aan iisolated ooutput iis rrequired, aa ddedicated iisolation ttransformermust bbe pprovided tto ppower tthe GGF-22100-AA/GF-22200-AA. The GGF-22100-AA/GF-22200-AA iis aa nnon-iisolated ddevice wwith aa hhalf-wwave rrectifier oon tthe 224VAC ppowerinput tterminal aat ppin 77. TTherefore, tto pprevent eequipment ddamage, mmultiple ddevices tthat aarepowered bby aa ccommon 224VAC ttransformer ooutput mmust uuse ccommon ddevice cconnections ((e.g. ppin 66{ground} tto oother ddevice gground, aand ppin 77 {{24VAC ppower} tto oother ddevice ppower), oor iindependentisolation ttransformers mmust bbe pprovided ffor eeach nnon-iisolated ddevice.The GGF-22100-AA/GF-22200-AA 224VAC gground aand AAnalog/PID OOutput ssignal rreturns aare ccommon.Therefore iit iis rrecommended tthat tthe AAnalog/PID OOutputs tto tthe BBAS ccontrol iinterface bbe cconnectedusing ttwo sseparate ttwisted sshielded ppair iin oorder tto eeliminate ppotential vvoltage ddrop oon tthe ccommon(from tthe 224VAC rreturn) tthat wwould ootherwise ccause iinaccurate rreadings.

3. Connect 24 VAC power to terminal 7, and the 24V ground at terminal 6 of the wiring terminal block as shown inFigures 5 and 6, observing the previous wiring precautions.

Analog/PID OOutput CConnectionsThe GF-2100-A/GF-2200-A provides two Analog/PID Outputs that can be configured as 0-10VDC, 0-5VDC or 2-10VDCand are capable of driving loads of up to 20mA (maximum). The 24VAC return ground connection is shared with theAnalog/PID Output signal grounds (GND). If the Analog/PID Outputs must be isolated from the 24VAC return, a dedicat-ed isolation transformer must be provided to power the GF-2100-A/GF-2200-A.

4. Connect OUT1 Analog/PID Output signal wire at terminal 3, and the signal ground at terminal 2 as shown inFigures 5 and 6 while observing the previous wiring precautions.

5. Connect OUT2 Analog/PID Output signal wire at terminal 1, and the signal ground at terminal 2 as shown inFigures 5 and 6 while observing the previous wiring precautions.

Form a “drip loop” with the the sensor probe cable at the transmitter if there is a potential for water runoff or condensation.

Alarm OOutput CConnectionsThe GF-2100-A/GF-2200-A provides an alarm output that can be configured as relay dry contacts, or as direct drive (15mA typical) for an external LED alarm indicator. The alarm output interface is set using the LED PWR jumper on the maincircuit board as shown in Figure 5. With the LED PWR jumper on, the alarm output is set to provide an external LED drive(15 mA typical) at terminal 4, with ground return at terminal 6. With the LED PWR jumper OFF, the alarm output is setto provide relay dry contacts between terminals 4 and 5 (contacts rated at 30VDC/24VAC 3 amps maximum). The Alarmcan be set as contacts close or contacts open on alarm as detailed in the Transmitter Setup menu later in this manual.

For external LED drive alarm output, ensure that the LED PWR jumper is installed, and connect the LED anode (+)to terminal 4, and cathode (-) at terminal 6. OR

For relay dry contact alarm output, ensure that the LED PWR jumper is removed, and connect the alarm wires toterminals 4 and 5. Contact rating is 30VDC/24VAC 3 amps maximum.

Sensor PProbe CConnectionWith 24VAC power OFF, connect each sensor probe cable plug to the transmitter by pushing it into the keyed cir-

cular receptacle (shown below) located at the bottom of the transmitter enclosure. Do not twist the connector.

Sensor probe cable plugs are “keyed”. Line up the connector plug with the transmitter receptacle and push straight on. DO NOTTWIST. Squeeze cable plug “ribs” towards receptacle when removing. Forcing the cable plug in or out of the receptacle will dam-age the connectors and void warranty.

Sensor probe must be connected to the transmitter before application of 24VAC power in order to properly “flash” sensor calibra-tion data to the transmitter.

Initial PPower UUpUpon application of 24VAC power, the GF-2100-A/GF-2200-A will initiate a brief self-test, indicated by dashed lines onthe LCD, and then will automatically engage the Start Up Menu to prompt the user through menus that configure thetransmitter for the specific installation/application. The Start Up menu will also be engaged each time power is appliedand the required area for any of the connected probes has not been set (*AR1(and/or AR2)=0.00 SQF). Refer to theStart Up Menu and Set Up menu details and descriptions later in this manual for a complete description of programmingoptions and features.

Operating MModesThe GF-2100-A/GF-2200-A provides two independent 12-bit (4096 discrete states) linear analog outputs. Each outputcan be independently enabled, disabled and configured within the Set Up Menu as follows:

Set as Standard flow or Temperature output from Flow 1 (and Flow 2) probes.Set as a PID Control output signal (with advanced PID control options available)Set as an airflow alarm status output (to indicate Hi limit, Low limit or Deadband with hysteresis conditions)Set as a temperature alarm output (to indicate Hi limit, Low limit or Deadband with hysteresis conditions)Set as Differential flow output to indicate the difference between Flow 1 and Flow 2 probes (GF-2200-A only)

In addition, the text displayed for each output on the GF-2100-A/GF-2200-A LCD display panel can be renamed to suityour specific requirements (5 characters max). Analog outputs are field selectable for 0-10VDC, 0-5VDC or 2-10VDC topermit simple integration with virtually all building automation systems. Refer to the Set up menu details and descrip-tions later in this manual for a complete description of analog output and PID control output options.

Alarm IInterface, OOptions aand DDescriptionsThe programmable alarm permits user selection of the alarm interface, alarm source and alarm type as follows:

Alarm IInterface ((LED PPWR JJumper)The alarm interface can be configured as relay dry contacts (30VDC/24VAC 3 amp maximum either N.O. or N.C.) or asdirect LED drive output (15 mA typical) using the LED PWR jumper on the transmitter circuit board shown in Figure 5.

Alarm SSource ((ALR SSRC=)The alarm source can be programmed within the Setup menu to monitor Probe 1 or Probe 2 airflow (ALR SSRC=FLOW),temperature (ALR SSRC=TEMP), or the difference in flow between Probes 1 and 2 (ALR SSRC=DIFF). It can also be set tomonitor the overall health/status of the transmitter and probe (ALR SSRC=TRBL)to activate an alarm in the event of a faultdetected in the sensor or transmitter.

Alarm TType ((ALR TTYP=)The alarm type can be set to monitor airflow or temperature and activate an alarm when airflow or temperature are abovea preset High Limit value (ALR TTYP=HI), below a preset Low Limit value (ALR TTYP=LO), or outside of a preset Deadbandoperating range (ALR TTYP=DEADB). The alarm hysteresis (ALRM HHYS=) value is used to establish a range as a percent-age above and below the alarm setpoint value.

The following alarm types are available in the Setup menu (refer to Setup Menu detail later in this document):

ALR TTYP=DEADB Sets alarm as Deadband type, where measurement outside of a range defined by the setpoint value (ASP=) plus or minus the hysteresis (ALRM HHYS=) value causes alarm activation. The alarm is reset when the measured value returns within this range.

ALR TTYP=HI Sets alarm as a Hi Limit type, where measurement above the ASP= value causes alarm activation. The alarm is reset when measurement decreases below the ASP= value minusthe ALRM HHYS= value.

ALR TTYP=LO Sets alarm as a Low Limit type, where measurement below the ASP= value causes alarm activation. The alarm is reset when measurement increases above the ASP= value plusthe ALRM HHYS= value.

ASP= (value) Sets the alarm setpoint measurement value that establishes alarm activity in conjunctionwith the other alarm options.

ALRM HHYS= (value) Sets the alarm range expressed as a percentage of the ASP= value.For ALR TTYP=DEADB, measured values outside of this range will trigger the alarm. For ALR TTYP=HI (and LO), the ALRM HHYS= value sets the range above or below the ASP=value where the alarm remains active once triggered.

ADEL= (value) Sets the delay period (in seconds) that the alarm condition must exist before the alarm output is activated.

ALRM PPOL= (value) Sets the relay dry contact configuration at terminals 4 and 5; For ALRM PPOL=NO, contacts are normally open and close on alarm; For ALRM PPOL=NC contacts are normally closed andopen on alarm.

The accuracy of the GF-2100-A/GF-2200-A is “percent of reading”, and is therefore not dependent on the full scale out-put range selected. However, if desired, the factory default full scale output range setting can be reconfigured in the field(see: CHANGING FACTORY DEFAULT SETTINGS).

CHANGING FACTORY DEFAULT SETTINGSSetup MMenu OOptionsThe GF-2100-A/GF-2200-A transmitter is configured at the factory to be fully operational when a sensor probe is con-nected and power is applied. Factory settings can easily be changed in the field through the Setup Menu, selected bysimultaneously pressing and releasing the “UP” and “DOWN” buttons while the transmitter is in its normal operatingmode (see Figure 11 for detailed flow chart of the Setup menu). Changes made in the Setup menu take effect immedi-ately. The following are common field changes to the factory default settings.

Output SScalingSensors are individually calibrated in wind tunnels (traceable to the National Institute of Standards and Technology[NIST]) between 0 and factory default full scale. Sensors are independent and produce “percent of reading” accuracy.Decreasing the full scale does not alter (or improve) the accuracy of the device. Factory default output scaling for theGF-2100-A/GF-2200-A can be changed by entering the setup menu through item *FS= setting (as shown in Figure 11).

Locking tthe CConfiguration SSettingsUsing the Lock Menu, transmitter configuration settings can be secured by entering a user defined lock code from 1 to9999. Once locked, user defined settings can only be altered after entering the defined lock code in the Initialization,IP/SI Units or Setup Menus. To enter the Lock Menu, press the “ESCAPE” and “UP” arrow simultaneously at any time.To enable the Lock Menu a code must be entered, and then verified. Figure 10 details the Lock menu.

TRANSMITTER CALIBRATIONThe GF-2100-A/GF-2200-A uses high quality industrial grade components and is designed for years of trouble-free oper-ation. Periodic recalibration of the transmitter is not required or recommended. Transmitter field calibration verifiers areavailable for purchase for installations requiring periodic validation. Contact factory for additional information.

FIELD ADJUSTMENTSThe GGF-22100-AA/GF-22200-AA iis ffactory ccalibrated aand sshould nnot rrequire aadjustment ((other tthan tthe iinstalled aaltitude)when ssensor pprobes aare iinstalled iin aaccordance wwith ffactory aapplication iinstallation gguidelines. Some installations how-ever, may not meet placement guidelines, or commissioning requirements may necessitate field adjustment. Fieldadjustment may improve the “installed accuracy” of the GF-2100-A/GF-2200-A when determining volumetric flow rates.

Altitude CCorrection AAdjustmentThe Altitude Correction Adjustment allows for correction of airflow readings at the installed site altitude and more pre-cise readings regardless on installed altitude. Refer to the Setup Menu Options, “*ALT=” menu item in Figure 11 toset this vale to the installation altitude.

Adjusting tthe LLow LLimit CCutoffThe low limit cutoff forces the analog airflow output signal to zero whenever the measured airflow rate falls below thespecified Low Limit value. This feature is useful on outside air intakes that often indicate false airflow rates, induced bytransient wind gusts or when the intake damper is closed and there is no net flow across the damper. Readings of 100FPM or more are not uncommon on many outside air intake applications when the intake damper is closed as a resultof air movement in the intake plenum and not a malfunction in the airflow measuring device. Setting the low limit to avalue significantly below the control setpoint and higher than the threshold flow for false wind readings simplifies con-trol and interpretation of the airflow rate signal on many applications. To set the low limit cutoff, enter Setup menu andset “*LL={desired value}” as shown in Figure 11.

Adjusting tthe DDigital OOutput FFilterThe digital output filter is useful for dampening signal fluctuations resulting from transient wind gusts on outdoor airintakes or excessive turbulence generated from duct disturbances. The digital output filter range can be set between 0(OFF) and 99%. Increasing the filter percentage limits the allowable change of the output signal. To change the amountof digital filtering, enter the Setup menu and set “*FILTER={desired value}” as shown in Figure 11.

Field CCalibration WWizard - AAdjustment oof FFactory CCalibration

Overview oof tthe FField CCalibration WWizardThe simple to use Field Calibration Wizard provides a one or two point menu driven field adjustment to factory calibra-tion of the airflow signal. The Field Calibration Wizard is most useful on larger duct sizes where the sensor density islower, and the installed accuracy uncertainty is greater. The Field Calibration Wizard allows engineers, contractors andowners to use stable and linear flow meters at a more affordable cost, where field adjustment is necessary or accept-able. This feature is especially valuable on outside air intake applications in close-coupled installations.

When evaluating the GF-2100-A/GF-2200-A using other reference airflow devices, ensure that the reference measure-ment device and the technique used to determine the airflow rate in the field are suitable for such measurement. Selecta location that is suitable for the reference measurement device, recognizing that this may not be the same locationwhere the GF-2100-A/GF-2200-A airflow station is installed. The inherent accuracy of the field reference measurementwill not be better than ±5% of reading and measurement uncertainty can often exceed ±10%. Do not adjust the outputof the GF-2100-A/GF-2200-A if the difference between the transmitter and the field reference measurement is less than10%. The following paragraphs detail use of the Field Calibration Wizard.

Fluctuations of airflow output signal are normal. Laboratory research indicates that dampening true fluctuations will result in poorcontrol and a larger dead-band of operation. Therefore, the use of the dampening filters in control devices is not recommended.

Problem Possible CCause RemedyNo LCD display indication and the green ACT LED onthe main circuit board is not illuminated.

Power is not available at transmitter. Apply 24VAC power to the transmitter.

Improper supply voltage to the power input terminalblock.

Ensure that 24VAC power is connected at terminal 7(ground at terminal 6) of the Wiring Terminal Block andthat with power applied to the transmitter, voltage isbetween 22.8 and 26.4 VAC.

Blown fuse. Check power wiring. Ensure that multiple devices wiredon a single transformer are wired "in-phase". Replacefuse only after the problem has been identified andcorrected, using an identical 1.0 amp, fast-acting fuse .

No LCD display indication and the green ACT LED onthe main circuit board is flashing.

LCD contrast too low. Adjust “LCD Contrast” potentiometer on the main cir-cuit board to improve display.

The LCD display is scrambled or there is no LCD displayindication after touching the switches, LCD display orcircuit board.

Static electricity. Touch an earth-grounded object, such as a duct, to dis-charge static electricity then reset the power. Avoiddirect contact with the LCD display or circuit board.

The LCD display indicates "No Probes". Power applied to transmitter before sensor probe wasconnected.

Cycle 24VAC power "OFF" and then back "ON" to thetransmitter.

The LCD display indicates "Too Many Sensors". Wrong probe connected to transmitter. Verify proper sensor probe/connection to transmitter.

The last character of the flow rate units is displayed asa lower case letter. (Also, to indicate when the FieldCalibration Wizard is engaged, the last character of theflow rate units is displayed as an upper case letter.)

The sensor detection system has detected a malfunc-tioning or missing sensor.

Check sensor probe cable connection. If connection isOK contact customer service for further assistance.

Wrong probe connected to transmitter. Verify proper sensor probe/connection to transmitter.

The green ACT LED on the main circuit board is steady"ON", not flashing.

Transmitter microprocessor is not running. Cycle 24VAC power "OFF" and then back "ON" to thetransmitter.

The green ACT LED on the main circuit board is flashingat 1-second intervals.

No problem, normal operation. No remedy required.

The green ACT LED on the main circuit board is flashingat 2-second intervals.

The sensor detection system has detected a malfunc-tioning or missing sensor.

Check sensor probe cable connection. If connection isOK contact customer service for further assistance.

Wrong probe connected to transmitter. Verify proper sensor probe/connection to transmitter.

The transmitter indicates airflow when the HVAC sys-tem is not operating.

Sensors are sensitive and will measure very low airvelocities. If a reading is indicated, there is airflowpresent where the airflow measuring station is located.

Do not attempt to adjust zero ("offset") since doing sowill result in an error in airflow measurement. The LowLimit airflow cutoff value can be set to force the outputsignal to zero at very low flows.

No analog output signal is measured at Analog Output(terminals 1 and/or 3 +, terminal 2 ground) of WiringTerminal Block of the transmitter.

Improper output wiring. Verify that 24VAC power is connected at pin 7, andground at pin 6 of the Wiring Terminal block.

Verify that the other non-isolated devices that are sup-plied with the same 24VAC power source are wired in-phase (24V power to 24VAC power, ground to ground).The power input of the transmitter is a half wave rectifi-er, and requires that all common devices be wired withcommon power and ground connections.

The Low Limit airflow cutoff value is above the actualairflow reading.

Decrease the Low Limit airflow cutoff value in theSetup Menu until it is below the actual airflow reading.

The analog output signal from the transmitter fluctu-ates while the airflow and/or temperature readings onthe LCD are steady.

Electrical interference from other devices is creatingnoise in the signal wires to the host control system.

The output signal wiring must be shielded. Individuallyground one or more of the following points: the signalwire shield at host controls; signal wire shield at thetransmitter, or pin 6 of the Wiring Terminal block of thetransmitter.

The LCD display does not match the readings indicatedby the host control system.

The scaling in the host control system is incorrect. Compare the current configuration of the transmitterwith that of the host control system. Compare the min-imum and full scale settings for each output by navigat-ing through the Setup Menu.
